1 5 Claims.

This invention relates to devices for waxing or lubricating yarns, threads and the like that are adapted to be used in connection with fabricforming machines such as knitting machines or for other purposes requiring lubricated yarn or,

thread. More particularly, this invention reiates to improvements in devices for mounting a cake of wax or lubricant and for directing a traveling yarn or thread over the wax or lubricant, wherein the wax or lubricant is continually presented to the traveling yarn or thread.

In former waxing or lubricating devices, the

- wax cake was mounted loosely on a spindle and although generally was free to rotate with the spindle, it had to be'fastened loosely to allow the wax cake to drop as it was expended, With this type of device, the wax cake wore unevenly and the wax was not applied uniformly.

The present invention overcomes the disadvantage of the device of the prior art, in that, with the present invention, the wax is continually directed toward the yarn and is guided during its movements so that the wax is directed toward 2 bore or recess II. An annular disc of normally solid wax is fixedly secured to the sleeve 9. The sleeve has a central bore therethrough, and is provided with a bearing i0, whereby the sleeve and wax cake may be mounted on the spindle 4 to freely revolve and slide longitudinally and axially thereon.

The outer diameter of the sleeve 9 is slightly less than the inner diameter of the guide bore i i. This permits th telescoping of the sleeve in the guide bore H, as the wax cake is expended. The length of the sleeve 9 is slightly greater than the guide bore l i, and is also slightly greater than the thickness of the wax cake so that the sleeve always extends into the bore to center the wax sleeve moves into the bore maintaining the cake .in proper alignment.

the yarn in proper alignment and uniformly applied thereto.

The principal object of the present invention is to provide a device for uniformly applying a normally solid lubricant to a yarn.

Another object of the present invention is to provide a device for mounting a cake of normally solid wax-like material in a predetermined position in relation to a traveling yarn and to continually present the cake of wax-dike material to the yarn.

Other objects and advantages of the invention will become apparent from the following description and the accompanying drawing.

In the drawings Figure 1 is an elevational view in section of a preferred embodiment of the invention, and

Figure 2 is an elevational view partly in sec;

tion of another embodiment of the invention.

spindle. This cup-like member 7 is provided at its upper face with a plane surface surrounded by an outwardly flaring flanged member l2, and at its center with an axially extending cylindrical The supporting plate member 2 is provided with yarn guide means 3 and M for guiding a traveling yarn over the face of the cup-like member. The plate-like member 2 is so mounted when in use that the spindle extends at an angle to the horizontal and when the cake of wax is mounted thereon it slides toward the guide bore ll and presses against the yarn passing over the face of member I.

In the operation of this device, the wax cake is in contact with the yarn passing over the face of the cup-like member and is caused to revolve by the traveling yarn as the wax is applied. As the wax or lubricant is expended, the sleeve -9 telescopes into guide bore ll, so that the wax is maintained in contact with the yarn with the surface thereof substantially in the plane of the path of travel of the yarn across the face of the cup-like member.

When the cake of wax has been expended, the sleeve 9 is withdrawn from the bore in the cuplike member and a new cake is concentrically mounted on the sleeve. The assembly is placed on the spindle.

The spindle may be mounted inclined to the horizontal at any angle up. to a right angle, but it is preferred to mount it at an angle of 30 to 35 with the horizontal, because at this angle the cake of wax and the cup-like member I will remain in place due to their own weight and will be freely rotatable on spindle 4, without exerting excessive pressure against the'traveling yarn.

In the modification of the invention shown in Figure 2, the sleeve 9 with a cake of wax-like material 20 fixedly supported thereon is held against the flat face on the front of the flaring flange member l2 by the action of the spring is on the spindle l'l acting on the sleeve 9 through the washer is, by virtue of the washer l 5 held by pin IE on the free end of the spindle ll, that retains the spring on the spindle. Sleeve 9 is flanged at its free end to hold wax cake 20 in position at its free end. With a device of this sort it is possible to operate this invention in the horizontal position and still get uniform wear on the cake and face of the member 1.

From the foregoing, it will be apparent that the present invention provides a new and improved waxing device wherein a solid cake of wax is fixedly secured to a rotatable sleeve, said device being faswned in a predetermined position in relation to s. yarn passing between a rotatable wax cake and a rotatable cup-like member, and while preferred embodiments of the invention have been disclosed herein, changes and variations in the invention may be made without departing from the spirit and scope or the invention as defined in the appended claims.

The terms yarn and "wax as used throughout the specification and claims are intended to include threads and fibers and all normally solid wax-like material used as a textile lubricant or finish respectively.

We claim:

1. A device for applying a normally solid waxlike material to a travelingyarri comprising a spindle, a member rotatably mounted on the spindle having a recess concentric with the spindle and having a plane surface surrounding the recess perpendicular to the spindle, and a sleeve having a smaller diameter than the recess rotatably and slidably mounted on the spindle, said sleeve serving to carry a wax cake fixedly secured thereabout and being adapted to telescope into the recess as the wax cake is expended, said sleeve being urged axially of the spindle toward the recess to press the wax cake against the plane surface of the member.

2. A device in accordance with claim 1 in which the sleeve has a length greater than the thickness at the wax cake and projects into the recess at all mes.

3. A device in accordance with claim 2 in which the plane surface is annular and concentric with the spindle.

4. A device in accordance with claim 3 in which the spindle is inclined to the horizontal whereby the sleeve is urged downwardly by gravity into the recess of the member.

5. A device for applying a normally solid waxlike material to a traveling yarn, comprising a spindle, a member rotatably mounted on the spindie having a recess concentric with the spindle and having a plane annular surface surrounding the recess, said surface being concentric with and perpendicular to the spindle, a sleeve having a smaller diameter than the recess rotatablv and slidably mounted on the spindle, said sleeve serving to can't a wax cake fixedly secured thereabout and heing adapted to telescope into the recess as the wax cake is expended, said sleeve having a length greater than the thickness of the wax cake and projecting into the recess at all times, and spring means tor urging the sleeve axially of the spindle into the recess to press the wax cake against the plane surface of the member.
